A motorcyclist struck in an alleged hit-and-run incident in Alice Springs last week has died in hospital after his life support was turned off.
NT Police confirmed the man's death on Thursday afternoon, just under a week since the crash in the Alice Springs CBD last Thursday night.
Police said charges would be upgraded for five teenagers arrested over the incident.
The man has been identified on social media as 47-year-old Alice Springs disability support worker Shane Powell.
Family friend Wayne Thompson said on Thursday the decision had been made to remove Mr Powell's life support.
"The doctors who have fought tirelessly can do no more and Shane's injuries to the brain are just too great," Mr Thompson said in a Facebook post.
He said Mr Powell was riding home from work when the crash happened.
"Shane really loved his work and was at the top of his game," he said.
Police allege the five people charged were all occupants of the car that hit Mr Powell at the intersection of Stott Terrace and Telegraph Terrace.
Two 19-year-old men and three youths — aged 16, 15 and 13 — face charges of hit-and-run causing serious harm and failing to rescue or provide help.
The 15-year-old boy has also been charged with entering an intersection against a red light.
Police said the younger three, who are all on bail, are due to face court tomorrow.
They said one 19-year-old had been remanded in custody until November 3 and the other, who is on bail, would face court at a later date.
